Error Handling
Use these routines to handle program errors.
Error-Handling Routines
| Routine | Use |
| assert macro | Test for programming logic errors; available in both the release and debug versions of the run-time library |
| _ASSERT, _ASSERTE macros | Similar to assert, but only available in the debug versions of the run-time library |
| clearerr | Reset error indicator. Calling rewind or closing a stream also resets the error indicator. |
| _eof | Check for end of file in low-level I/O |
| feof | Test for end of file. End of file is also indicated when _read returns 0. |
| ferror | Test for stream I/O errors |
| _RPT, _RPTF macros | Generate a report similar to printf, but only available in the debug versions of the run-time library |
